WATER-CLOSET.

Specification of Letters Patent.

Application filed April 25, 1910. Serial N 0. 557,347.

To all whom it may concern:

Be it known that I, WILLIAMA. RAT- CLIFFE, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Tater-Closets, of which the following is a specification.

The main objects of the are to provide a water the closet substantially unmixed with air and at a level only slightly above the normal level of the water in the bowl of the closet.

1 A specific embodiment of this invention is shown in the accompanying drawings. wherein Figure l is a perspective view of the closet and its tlush' the valve to the intake.

In the construction shown, the water closet comprises a vitreous bowl 1 of ordinary shape, provided with a siphonic outlet is a hollow rim 3 having jet openings 4 for delivering water to wash down the sides of the bowl. The channel of the hollow rim communicated with a chamber 5 located back directly against above the upper bend of the slphonic outl end into chamber 7, and communicating at its upper end with chamber 5. Through this intake conduit, water is delivered to the siphon jet 6, and also hollow rim 3. The inlet conduit is located in the side of the conduit, and opens laterally, and is located only slllighfily above the water in t substantially unmixedwith air.

The fl type shown in detail in the United States patent to Brooks No. 876,518, issued January 14,

1908, though it is to be understood that the details of the valve may be varied without ASSIGNOR 'IO CHARLES C. STRINGER,

bowl and its outlet conduit, is opening at its lower to the jets of the 9;. 10 of the intake 1 ushing valve may be of the general departing from the spirit of my invention as herein set forth and claimed.

In the construction shown, the flushing valve 12 comprises a valve-casing having at its lower end a tubular inlet 13 with a suitable turn valve 14. Th

has a tubular outlet 15. t0 which the conhaving a head 18, cooperating with the valve-seat 16 to hold the check until its release e valve casing also Y in a button or knob 23. Within the easing 22 are the elements for timing the operation of the valve, but these may vary in detail, and need not'be described here.

The construction shown is somewhat shorter from front to back than many siphon jet closets, and has the advantage that it may be placed with its back directly against the wall of the room. If, for any reason, it becomes necessary to detach the flushing valve, this may be done without drawing the water-seal from the bowl. Furthermore if for any reason the supply of water should fail, there is no danger that an inadvertent opening of will cause water from the bowl to be siphoned back into the water mains of the house, as would be the case if the intake inlet were located below the normal water level of the bowl.

The operation of the structure above described is as follows: With water pressure on the valve, and water at normal level in the bowl, the depression of the vertical push rod and the consequent unseating of the valve plunger allows water to enter the valve and to then rush across through the short horizontal connector 11 and into the intake conduit 9. The water enters the intake conduit just above the level of the water then in the conduit, and then rises through the upper leg of the conduit. into the chamber 5 and into the hollow rim 3. It does this without mixing with the air initially contained in these channels. Whatever air may have been initially in the valve casing and the short connector 11 is forced forward ahead of the water and passes upward into the chamber 5 and out through rim 3. The total absence of any air trap,; delivery of the water into the and the direct intake conduit just above the level of the water normally standing in the conduit eliminates in a large measure the gurgling and splashmg sound ordinar1ly experience with other closets wherein the water is delivered to chamber 5 at its top or rear.

While the water is rising into chamber 5 and expelling the air therefrom, the increased pressure starts the siphon jet 6 and begins the movement of the soil backward up the siphon conduit. The siphon jet is well in action before the wash-down jets 4t begin to deliver water to the bowl. This eliminates the churning action in the bowl sometimes found in closets wherein the inlet is so positioned that the hollow rim comes into play before the siphon jet. The

action of the siphon jet is practically instantaneous, and the water in the bowl begins to recede before the washing water the water i from jets 4 has a chance to raise level in the bowl.

What I claim as new, and desireto secure by Letters Patent of the United @tates is:

the flushing valve 1. The combination of a water closet bowl, a hollow rim encircling said bowl and having jet openings for water, a siphonic outlet conduit positioned back of said bowl. and there forming a water seal, a jet orifice arranged to project water upward along said conduit, an intake conduit at the side of said bowl and integral therewith, said intake conduit having an inlet in its side which opens laterally and is above the normal level of water in said bowl and is below said hollow rim, said intake conduit being arrange to convey water to said hollow rim after delivery of water to said jet orifice, a flushing va ve close to the side of said bowl and having its main valve seat located as low, at least, as said inlet and in direct alinement therewith, and a short straight horizontal pipe connecting said valve with said intake.

2. The combination of a vitreous water closet having a bowl and a siphonic outlet conduit at the back thereof forming a water seal, said bowl having a hollow rim encircling said bowl with jet openings for wash-down water, a supply chamber for said rim located above said siphon conduit, an intake conduit integral with said bowl and extending along the side thereof and having an outlet for delivering water upward to said supply chamber for delivery to said hollow rim, said conduit having an inlet which opens laterally at the side of said bowl slightly above the normal water level in said bowl and somewhat below the supply chamber of said rim, a flushing valve close to the side of said bowl and having a side opening in direct alinement with the inlet of said intake conduit, and a short straight horizontal connector joining said valve to said intake conduit and affording a direct and straight path for water from the seat of said valve to said inlet.

3. The combination of a vitreous water closet having a bowl and a siphonic outlet conduit at the back thereof forming a water seal, said bowl having a supply chamber leading to a hollow rim encircling the bowl and provided with jet openin s for water, an intake conduit integral witi said bowl and extending downward along said bowl at the side of said outlet conduit, a water chamber located between the legs of said siphonic conduit and communicating with said inlet conduit to receive water therefrom, said water chamber having a jet opening directed upward along said siphonic conduit, said intake conduit having an inlet which opens laterally at a level slightly above the normal water level in said bowl and somewhat below the supply chamber of said hollow rim, whereby said siphon jet comes into action before the jets of said hollow rim, a flushing valve close to the side of said 7 bowl and directly in alinei ment with said inlet, and a short straight my hand this twenty-first day of April,
